• apache tomcat 8 websocket origin and client address

  - by user2926082

  i hope someone can help me ... i am using apache tomcat 8.0.0-RC5 and JSR-356 web socket API ... I have 2 questions: 1) Is it possible to get the client ip on @OnOpen method ?? 2) Is it possible to get the origin of the connection ??? I followed the websocket example which comes with the distribution of tomcat and i was not able to find the answers .... My java class is basically as follow @ServerEndpoint(value = "/data.socket") public class MyWebSocket { @OnOpen public void onOpen(Session session) { // Here is where i need the origin and remote client address } @OnClose public void onClose() { // disconnection handling } @OnMessage public void onMessage(String message) { // message handling } @OnError public void onError(Session session, Throwable throwable) { // Error handling } }

• PNG alpha rendered as black in Blender

  - by Camilo Martin

  I'm a Blender novice, so this is probably easy to fix. When I use a transparent PNG as a texture in Blender, the parts that should be transparent are rendered as black. This is especially confusing since in the material preview it looks as if the material would indeed be transparent. Here's a screenshot: This is the test texture, and in the right on top of a checkerboard:                        Here is the .blend file in case you want to check it:

• Cloning Fresh Windows 7 with external HDD, DVD or CDs?

  - by hhh

  I want to create Windows installation disk (not necessarily CD) from my Windows 7 Pro laptop, not sure what it actually means here. The material is about 50-60GB, requiring about 12 pcs of 5GB disk (not going to happen, too much work to use them later). I have the Windows serial on the laptop bottom and this is so-called firm -laptop (no idea what it actually mean, better warranty and some instant support thing apparently). Now how to do the clone with external material such as DVDs? how can I create mock-windows-installation medium or some real windows-installation medium? I am now not sure whether Windows offers W7 -installations medium online, well my W -peer mentioned some MSDAA -something. Perhaps related Cloning Fresh Windows 7 -fsed HDD to Linux Server because having no external HDD or disks for the Backup

• Questions, Knowledge Checks and Assessments

  - by ted.henson

  Questions should be used to reinforce concepts throughout the title. You have the option to include questions in the course, in assessments, in Knowledge Checks, or in any combination. Questions are required for creating knowledge checks and assessments. It is important to remember that questions that are not in assessments are not tracked. Be sure to structure your outline so that questions are added to the appropriate assignable unit. I usually recommend that questions appear directly below their relative section. This serves two purposes. First, it helps ensure that the related content and question stay relative to one another. Secondly, it ensures that when the "link to subject" option is used it will relate back to the relative content. Knowledge checks are created using the questions that have been added to the related assignable unit. Use Knowledge Checks to give users an additional opportunity to review what they have learned. Knowledge Check allows users to check their own knowledge without being tracked or scored. Many users like having this self check option, especially if they know they are going to be tested later. Each assignable unit can have its own Knowledge Check. Assessments provide a way to measure knowledge or understanding of the course material. The results of each assessment are scored and tracked. Assessments are created using the questions that have been added to the relative assignable unit(s). Each assignable unit, including the Title AU, can have multiple assessments. Consider how your knowledge paths will be structured when planning your assessments. For instance, you can create a multiple-activity knowledge path, with multiple assessments from the same title or assignable unit. Also remember, in Manager an assessment can be either a pre or post assessment. Pre-assessments allow the student to discover what is already known in a specific topic or subject and important if the personal course feature is being used. Post-assessments allow you test the student knowledge or understanding after completing the material.

• Questions about Mac Book Pro Keyboard and shortcuts

  - by SimonSolnes

  I have been researching a lot about this and I cannot seem to find any useful information about this topic, what so ever. I have now been using Ubuntu in one week, and have gotten pretty confident with almost everything. Except keyboard layout and shortcuts. If you know a tutorial or a documents explaining keyboard shortcuts in Ubuntu or linux in general, can you please list it? I use a Mac Book Pro with a Norwegian keyboard, and I have several questions about this: Is there a program for having a consise list of absolutely all keyboard shortcuts, and be able to change them? How do I use my fn keys? (fn button doesnt do the job for some reason) How can I use my alt+letter-key-or-number-key or alt+shift+letter-key-or-number-key to get fancy characters. (Like I do on Mac OS X) How can I swap cmd and ctrl key system wide? Also I really want to be oriented around this subject, since this is the only thing holding me back on Ubuntu, so if there exists some in-depth material on this, it would be great. Also, if there exists some programs or material out there making it easier with Mac hardware I would enjoy that. Sorry if my questions seems vague. Thank you very much Simon

• SlimDX and Parsing .X Files

  - by P. Avery

  I'm trying to parse a .x file using SlimDX. I can create the XFile object and register templates but I'm having problems with the enumeration object. The enumeration object has a child count of 0 for a file I know to have valid data. Here is code to create file, enumeration, and data objects: public void Parse(string filename, string templates, ref Frame aParam) { XFile xfile = null; XFileEnumerationObject enumObj = null; XFileData dataObj = null; // create file object xfile = new XFile(); // register templates if (xfile.RegisterTemplates(XFile.DefaultTemplates).IsFailure) { Console.WriteLine(Result.Last); xfile.Dispose(); return; } // create enumeration object enumObj = xfile.CreateEnumerationObject(filename, System.Runtime.InteropServices.CharSet.Auto); if (enumObj == null) { xfile.Dispose(); return; } // get child count( returns 0 here ) long ncElements = enumObj.ChildCount; for (int i = 0; i < ncElements; ++i) { // never reached... dataObj = enumObj.GetChild(i); if (dataObj.IsReference) continue; try { Parse(dataObj, ref aParam); } catch (Exception e) { e.Write(); } finally { dataObj.Dispose(); } } enumObj.Dispose(); xfile.Dispose(); } ...There are no exceptions thrown by this function...the child count is 0 so the conditional loop breaks right away, the file objects are disposed of and the function returns... Here is .x file...a simple cube: xof 0303txt 0032 Frame Root { FrameTransformMatrix { 1.000000, 0.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 0.000000, 1.000000;; } Frame Cube { FrameTransformMatrix { 1.000000, 0.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 0.000000, 1.000000;; } Mesh Cube{ //Cube Mesh 36; -1.000000; 1.000000; 1.000000;, -1.000000;-1.000000; 1.000000;, 0.999999;-1.000001; 1.000000;, -1.000000;-1.000000;-1.000000;, 1.000000;-1.000000;-1.000000;, 0.999999;-1.000001; 1.000000;, 1.000000; 0.999999; 1.000000;, -1.000000; 1.000000; 1.000000;, 0.999999;-1.000001; 1.000000;, -1.000000; 1.000000;-1.000000;, -1.000000;-1.000000;-1.000000;, -1.000000; 1.000000; 1.000000;, -1.000000; 1.000000; 1.000000;, 1.000000; 0.999999; 1.000000;, 1.000000; 1.000000;-1.000000;, 1.000000; 0.999999; 1.000000;, 0.999999;-1.000001; 1.000000;, 1.000000;-1.000000;-1.000000;, -1.000000;-1.000000;-1.000000;, -1.000000;-1.000000; 1.000000;, -1.000000; 1.000000; 1.000000;, 1.000000; 1.000000;-1.000000;, 1.000000;-1.000000;-1.000000;, -1.000000; 1.000000;-1.000000;, 1.000000; 1.000000;-1.000000;, 1.000000; 0.999999; 1.000000;, 1.000000;-1.000000;-1.000000;, -1.000000; 1.000000;-1.000000;, -1.000000; 1.000000; 1.000000;, 1.000000; 1.000000;-1.000000;, -1.000000;-1.000000; 1.000000;, -1.000000;-1.000000;-1.000000;, 0.999999;-1.000001; 1.000000;, 1.000000;-1.000000;-1.000000;, -1.000000;-1.000000;-1.000000;, -1.000000; 1.000000;-1.000000;; 12; 3;0;1;2;, 3;3;4;5;, 3;6;7;8;, 3;9;10;11;, 3;12;13;14;, 3;15;16;17;, 3;18;19;20;, 3;21;22;23;, 3;24;25;26;, 3;27;28;29;, 3;30;31;32;, 3;33;34;35;; MeshNormals { //Mesh Normals 36; 0.000000;-0.000000; 1.000000;, 0.000000;-0.000000; 1.000000;, 0.000000;-0.000000; 1.000000;, -0.000000;-1.000000;-0.000000;, -0.000000;-1.000000;-0.000000;, -0.000000;-1.000000;-0.000000;, -0.000000;-0.000000; 1.000000;, -0.000000;-0.000000; 1.000000;, -0.000000;-0.000000; 1.000000;, -1.000000; 0.000000;-0.000000;, -1.000000; 0.000000;-0.000000;, -1.000000; 0.000000;-0.000000;, 0.000000; 1.000000; 0.000000;, 0.000000; 1.000000; 0.000000;, 0.000000; 1.000000; 0.000000;, 1.000000;-0.000001; 0.000000;, 1.000000;-0.000001; 0.000000;, 1.000000;-0.000001; 0.000000;, -1.000000; 0.000000;-0.000000;, -1.000000; 0.000000;-0.000000;, -1.000000; 0.000000;-0.000000;, 0.000000; 0.000000;-1.000000;, 0.000000; 0.000000;-1.000000;, 0.000000; 0.000000;-1.000000;, 1.000000; 0.000000;-0.000000;, 1.000000; 0.000000;-0.000000;, 1.000000; 0.000000;-0.000000;, 0.000000; 1.000000; 0.000000;, 0.000000; 1.000000; 0.000000;, 0.000000; 1.000000; 0.000000;, -0.000000;-1.000000; 0.000000;, -0.000000;-1.000000; 0.000000;, -0.000000;-1.000000; 0.000000;, 0.000000;-0.000000;-1.000000;, 0.000000;-0.000000;-1.000000;, 0.000000;-0.000000;-1.000000;; 12; 3;0;1;2;, 3;3;4;5;, 3;6;7;8;, 3;9;10;11;, 3;12;13;14;, 3;15;16;17;, 3;18;19;20;, 3;21;22;23;, 3;24;25;26;, 3;27;28;29;, 3;30;31;32;, 3;33;34;35;; } //End of Mesh Normals MeshMaterialList { //Mesh Material List 1; 12; 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0;; Material Material { 0.640000; 0.640000; 0.640000; 1.000000;; 96.078431; 0.500000; 0.500000; 0.500000;; 0.000000; 0.000000; 0.000000;; TextureFilename {"Yellow.jpg";} } } //End of Mesh Material List MeshTextureCoords UVMap{ //Mesh UV Coordinates 36; 0.000000; 1.000000;, 1.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 1.000000;, 0.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 1.000000;, 1.000000; 0.000000;, 1.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 0.000000;, 0.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 0.000000;, 0.000000; 1.000000;, 1.000000; 1.000000;, 1.000000; 0.000000;; } //End of Mesh UV Coordinates } //End of Mesh Mesh } //End of Cube } //End of Root Frame

• How to fix bad Collada produced by FBX?

  - by David

  I tried to use the FBX SDK (2011.3.1) to load FBX files and save them as Collada files in order to be able to import FBX files in Panda3D. Unfortunately the resulting Collada files are not usable for several reasons, among them: There's a Maya specific extra technique diffuse <diffuse> <texture texture="Map__2-image" texcoord="CHANNEL0"> <extra> <technique profile="MAYA"> <wrapU sid="wrapU0">TRUE</wrapU> <wrapV sid="wrapV0">TRUE</wrapV> <blend_mode>ADD</blend_mode> </technique> </extra> </texture> </diffuse> It assigns a texcoord channel name that isn't referenced anywhere else in the file (in the previous code sample, no geometry uses "CHANNEL0"...) Every polygon is exported twice, a first time with a basic material (only diffuse color, specular color, etc.) and a second time with a textured material -- this doubles the number of polygons of each model without any valuable reason Anyway, the resulting Collada file cannot be opened correctly either with OpenCOLLADA or Panda3D's "dae2egg". Anyone has any experience on how to "fix" it and make it understandable by common and well-reputed Collada importers such as OpenCOLLADA?

• The Case of the Invisible Training Resource

  - by GGBlogger

  I’ve been at this programming business longer than I would like to admit. For that reason I am always looking for new training resources as anyone in this business knows all too well. I’ve looked at AppDev (way too expensive for my meager budget), LearnVisualStudio (I have a lifetime subscription), and several others. What appears to be a new version of AppDev called LearnDevNow has some good material and so it goes. So what does all this have to do with the title? I’ve been using Adobe’s Flex Builder 3 and now their latest Flash Builder 4 (a renaming of the Adobe Flex development environment). One of the offered perks on registering was a month’s subscription to Lynda.com. My first reaction was “What the heck is Lynda.com?” but I chose it and signed up. What a surprise I was in for. I’d never heard of them before but discovered one of the most comprehensive training resources I’ve ever seen – and all for $ 34.95 a month in the version that offers Exercise files. They do have a heavy focus on Adobe products but also cover a lot of Microsoft material. What bothered me is that in the time I’ve been in this business I’d never heard of them! ; Thus the allusion to “The Invisible Training Resource.” Not only do they offer beginner and in depth training but the syllabus and the instructors are some of the best I’ve seen in the industry. So I just feel that more folks need to know about this organization. If you need training in the venues they offer I can attest to the fact that they offer some of the best training available in this industry in my humble opinion. You really owe it to yourself to check out Lynda.com.

• Entity system and rendering types

  - by Papi75

  I would like to implement entity system in my game and I've got some question about entity system and rendering. Currently, my renderer got two types of elements: Current design Mesh : A default renderable with a Material, a Geometry and a Transformable Sprite : A type of mesh with some methods like "flip" and "setRect" methods and a rect member (With an imposed geometry, a quad) This objects inherit from "Spacial" class. Questions: How can I handle this two types in an entity system? I'm thinking about using "MeshComponent" and "SpriteComponent", but if I do that, an entity could have a Mesh and a Sprite at the same type, it's look stupid, right? I thought the idea to have a parent "rendering" component : "RenderableComponent" for "MeshComponent" and "SpriteComponent" but it will be difficult to handle "cast" in the game (ex: did I need to ask entity-getComponent or SpineComponent, …) Thanks a lot for reading me! My entity system work like that: --------------------------------------------------------------------------- Entity* entity = world->createEntity(); MeshComponent* mesh = entity->addComponent<MeshComponent>(material); mesh->loadFromFile("monkey.obj"); PhysicComponent* physic = entity->addComponent<PhysicComponent>(); physic->setMass(5.4f); physic->setVelocity( 0.5f, 2.f ); --------------------------------------------------------------------------- class RenderingSystem { private: Scene scene; public: void onEntityAdded( Entity* entity ) { scene.addMesh( entity->getComponent<MeshComponent>() ); } } class PhysicSystem { private: World world; public: void onEntityAdded( Entity* entity ) { world.addBody( entity->getComponent<PhysicComponent>()->getBody() ); } void process( Entity* entity ) { PhysicComponent* physic = entity->getComponent<PhysicComponent>(); } } ---------------------------------------------------------------------------

• Using Lerp to create a hovering effect for a GameObject

  - by OhMrBigshot

  I want to have a GameObject that has a "hovering" effect when the mouse is over it. What I'm having trouble with is actually having a color that gradually goes from one color to the next. I'm assuming Color.Lerp() is the best function for that, but I can't seem to get it working properly. Here's my CubeBehavior.cs's Update() function: private bool ReachedTop = false; private float t = 0f; private float final_t; private bool MouseOver = false; // Update is called once per frame void Update () { if (MouseOver) { t = Time.time % 1f; // using Time.time to get a value between 0 and 1 if (t >= 1f || t <= 0f) // If it reaches either 0 or 1... ReachedTop = ReachedTop ? false : true; if (ReachedTop) final_t = 1f - t; // Make it count backwards else final_t = t; print (final_t); // for debugging purposes renderer.material.color = Color.Lerp(Color.red, Color.green, final_t); } } void OnMouseEnter() { MouseOver = true; } void OnMouseExit() { renderer.material.color = Color.white; MouseOver = false; } Now, I've tried several approaches to making it reach 1 then count backwards till 0 including a multiplier that alternates between 1 and -1, but I just can't seem to get that effect. The value goes to 1 then resets at 0. Any ideas on how to do this?

  As you know, JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. It was a resounding success with a great vibe, excellent technical content and numerous world class speakers, both local and international. Various folks like Tori Wieldt, Steve Chin, Arun Gupta, Bruno Borges and myself looked at the conference from slightly different colored lenses. It's interesting to put them all together in a panoramatic collage: Tori wrote about the Sao Paulo Geek Bike Ride held the Saturday before the conference here (enjoy the photos and video). She also discusses the keynotes in great detail here. Steve looked at it from the viewpoint of someome instrumental to putting the event together. Read his thoughts here (he has more geek bike ride photos as well as material for his JavaFX/HTML 5 talk). Arun had a more holistic view of the conference. He covers the geek bike ride, the GlassFish party (organized by Bruno Borges), his Java EE talks, and more. Check out the cool photos as well as the technical material. Bruno provides the critical local perspective in his 7 reasons you had to be at JavaOne Latin America 2012. He discusses the OTN Lounge, the hands-on-lab, the Java community keynote, Java EE technical sessions and of course the GlassFish party! I covered the GlassFish booth, the lab and my technical sessions (as well as Sao Paulo's lively metal underground) here.

• Writing to a D3DFMT_R32F render target clamps to 1

  - by Mike

  I'm currently implementing a picking system. I render some objects in a frame buffer, which has a render target, which has the D3DFMT_R32F format. For each mesh, I set an integer constant evaluator, which is its material index. My shader is simple: I output the position of each vertex, and for each pixel, I cast the material index in float, and assign this value to the Red channel: int ObjectIndex; float4x4 WvpXf : WorldViewProjection< string UIWidget = "None"; >; struct VS_INPUT { float3 Position : POSITION; }; struct VS_OUTPUT { float4 Position : POSITION; }; struct PS_OUTPUT { float4 Color : COLOR0; }; VS_OUTPUT VSMain( const VS_INPUT input ) { VS_OUTPUT output = (VS_OUTPUT)0; output.Position = mul( float4(input.Position, 1), WvpXf ); return output; } PS_OUTPUT PSMain( const VS_OUTPUT input, in float2 vpos : VPOS ) { PS_OUTPUT output = (PS_OUTPUT)0; output.Color.r = float( ObjectIndex ); output.Color.gba = 0.0f; return output; } technique Default { pass P0 { VertexShader = compile vs_3_0 VSMain(); PixelShader = compile ps_3_0 PSMain(); } } The problem I have, is that somehow, the values written in the render target are clamped between 0.0f and 1.0f. I've tried to change the rendertarget format, but I always get clamped values... I don't know what the root of the problem is. For information, I have a depth render target attached to the frame buffer. I disabled the blend in the render state the stencil is disabled Any ideas?

• The Developers Conference 2012: Presentation about CEP & BAM

  - by Ricardo Ferreira

  This year I had the pleasure again of being one of the speakers in the TDC ("The Developers Conference") event. I have spoken in this event for three years from now. This year, the main theme of the SOA track was EDA ("Event-Driven Architecture") and I decided to delivery a comprehensive presentation about one of my preferred personal subjects: Real-time using Complex Event Processing. The theme of the presentation was "Business Intelligence in Real-time using CEP & BAM" and I would like to share here the presentation that I have done. The material is in Portuguese since was an Brazilian event that happened in São Paulo. Once my presentation has a lot of videos, I decided to share the material as a Youtube video, so you can pause, rewind and play again how many times you want it. I strongly recommend you that before starting watching the video, you change the video quality settings to 1080p in High Definition.

• How can I make an infinite cave using stage3d?

  - by ifree

  I want to make an infinite cave in my 3d game using flash stage3d. But I got no idea about how to build that cave. Can anyone can give me some solution or hint? update: I've tried agal fragment shader like squeae tunnel in shader toy code: var fragmentProgramCode:String = AGALUtils.build() .mov("ft0","v0") .div("ft1","ft0.xy","fc3.xy") .mul("ft2","fc6.x","ft1") .sub("ft3","ft2","fc5.x")//vec2 p = -1.0 + 2.0 * gl_FragCoord.xy / resolution.xy; .mul("ft1","ft3.x","ft3.x") .mul("ft2","ft3.y","ft3.y") .pow("ft4","ft1","fc6.z")//float r = pow( pow(p.x*p.x,16.0) + pow(p.y*p.y,16.0), 1.0/32.0 ); .pow("ft5","ft2","fc6.z") .add("ft1","ft4","ft5") .pow("ft4","ft1","fc6.w") .mov("ft5","fc5")//uv .sub("ft1","fc7.x","ft4") .add("ft5.x","fc7.x","ft1")//uv.x = .5*time + 0.5/r; .mov("ft6","fc0")//for atan .atan2("ft5.y","ft3.y","ft3.x",new <String>["fc7.y","fc5.x","fc7.z","fc7.w","fc8.x","fc8.y","fc8.z","fc8.w","fc9.x","fc9.y"],"ft6") .tex("ft0","ft5","fs0","repeat","linear","nomip")//tex .mul("ft1","ft4","ft4") .mul("ft2","ft1","ft4")//r*r*r .mul("ft1","ft0.xyz","ft2") .mov("ft0.w","fc5.x") .mov("oc","ft1").toString() it can only apply one material,but my project requires different types of material (like floor,ceilling). so ,I create a 3d model Is there anyway to make that 3d model render like "infinity cave"? use agal to make each side of cave's texture move? thanks for your help

• Does anybody know of any resources to achieve this particular "2.5D" isometric engine effect?

  - by Craig Whitley

  I understand this is a little vague, but I was hoping somebody might be able to describe a high-level workflow or link to a resource to be able to achieve a specific isometric "2.5D" tile engine effect. I fell in love with http://www.youtube.com/watch?v=-Q6ISVaM5Ww this engine. Especially with the lighting and the shaders! He has a brief description of how he achieved what he did, but I could really use a brief flow of where you would start, what you would read up on and learn and the logical order to implement these things. A few specific questions: 1) Is there a heightmap on the ground texture that lets the light reflect brighter on certain parts of it? 2) "..using a special material which calculates the world-space normal vectors of every pixel.." - is this some "magic" special material he has created himself, or can you hazard a guess at what he means? 3) with relation to the above quote - what does he mean by 'world-space normal vectors of every pixel'? 4) I'm guessing I'm being a little bit optimistic when I ask if there's any 'all-in-one' tutorial out there? :)

• Submitting software to a competition, it becomes their property?

  - by myrkos

  So I'm about to submit a game to a competition, but as I looked through the rules a chunk grabbed my attention: All Entries become the sole and exclusive property of Sponsor and will not be acknowledged or returned. Sponsor shall own all right, title and interest in and to each Entry, including without limitation all results and proceeds thereof and all elements or constituent parts of Entry (including without limitation the Mobile App, the Design Documents, the Video Trailer, the Playable and all illustrations, logos, mechanicals, renderings, characters, graphics, designs, layouts or other material therein) and all copyrights and renewals and extensions of copyrights therein and thereto. Without limitation of the foregoing, each Eligible Entrant shall and hereby does absolutely and irrevocably assign and transfer all of his or her right, title and interest in his or her Entry to Sponsor, and Sponsor shall have the right and may authorize others to use, copy, sublicense, transmit, modify, manipulate, publish, delete, reproduce, perform, distribute, display and otherwise exploit the Entry (and to create and exploit derivative works thereof) in any manner, including without limitation to embody the Entry, in whole or in part, in apps and other works of any kind or nature created, developed, published or distributed by Sponsor and to and register as a trademark in any country in Sponsor’s name any component of the Entry, without such Eligible Entrant reserving any rights or claims with respect thereto. Sponsor shall have the exclusive right, in perpetuity, throughout the Territory to change, adapt, modify, use, combine with other material and otherwise exploit the Entry in all media now known or hereafter devised and in any manner, in its sole and absolute discretion, without the need for any payment or credit to Entrant. So the game will become the sponsor's property; however, they don't ask for source code. So will I still own the rights to the source code, whatever that means? And if it doesn't win said competition, will I be able to publish it myself without their trademarks? I am very new to software legality stuff, so I would appreciate any clarification. Since there's a possibility I won't even own the source, is it possible to make the game core engine open source software with a not-very-restrictive license and include that in the project, so I at least still own the game engine? Or does it not work that way?

• Sorting objects before rendering

  - by dreta

  I'm trying to implement a scene graph and in all the articles i've come across there is talk about object sorting. So you'd sort your objects by "material" for example. Now untill i sat down and started implementing it, i kind of took this for granted, because it made sense. But now i'm wondering what does sorting actually change? In my engine, i have a manager for UBOs, i use those to store data that'll be shared between programs, at the moment that only involves time, camera and projection matrices and lights (i'm not worrying about managing which lights affect which objects ATM). Now for each model i have to change the model to world matrix uniform, no sorting is going to change that. So is the jump from changing this matrix to also setting a material for each object that bad? I vaguely remember reading somewhere that each time you change something in the pipeline, it has to get flushed and that can cause performance issues. But for each drawing call i'm setting up a model to world matrix anyway, so what sense does it make to ever be concerned about this? BTW is there any information about whether changing a uniform and calling glBufferSubData is more (or less) expensive.

• How To Check If a Transaction Related to Oracle Asset Tracking Has Been Accounted in SLA

  - by LuciaC-Oracle

  In Oracle Asset Tracking (OAT), we often see situations where a pending transaction has failed to be processed by the OAT programs. Typical situations can be: a pending transaction errors with "Unable to derive accounts from sub ledger accounting for the material transaction" a transaction is not picked by OAT programs. The Create Accounting program log file will show error messages and possible corrective actions to solve the error.  But as this is usually a scheduled program, often any errors that are reported are missed by users. To aid OAT users to identify if a transaction has failed and accounting has not been created, we have now created a SQL script which can be run for any pending transaction: How To Check If a Transaction Related to Oracle Asset Tracking Has Been Accounted in SLA ? (Doc ID 1673414.1)Using the script in this note, the user can pass the material transaction ID for the related transaction and the script will check if SLA accounting entries have been created for this specific transaction or not.If the SLA accounting entries have not been created, the script will prompt the user to run Create Accounting program.  After Create Accounting has been run, the user can run the script again to confirm that accounting has been created.

• Collision planes confusion

  - by Jeffrey

  I'm following this tutorial by thecplusplusguy and in the linked video he explain that for example for the world basement and walls we need to create the actual rendered (shown to the player) walls and then duplicate them, place them in the same coordinates as the rendered walls and call them collision (by defining their material to collision). Then it defines in the Object loader function that those objects with material == collision are collision planes and should not be rendered but just used to check collision. Now I'm pretty confused. Why would we add this kind of complexity to a problem that can easily be solved by a simple loadObject(string plane_object, bool check_collision);: Creating only the walls object (by loading .obj file in plane_object) Define them also as collision planes whenever the check_collision is set to true In this case we have lowered the complexity of his method and make it more flexible and faster to develop (faster because we don't always have to make a copy for each plane and flexible because we don't hardcode the Object loader). The only case in which this method could not work is when we need hidden collision planes, and for that we could modify the loadObject() function like this: loadObject(string plane_object, bool check_collision = true, bool hide_object = false); Creating only the walls object (by loading .obj file in plane_object) Define them also as collision planes whenever the check_collision is set to true And add the ability to actually show the object or hide it based on hide_object. The final question is: am I right? What would the possible problem encountered with my solution versus his?
